When Ethernet is selected under Interface Configuration
Example: To communicate with two MICRO/Is and a computer via Ethernet
Set MICRO/I A, MICRO/I B, and the computer all to the same values: subnet mask 255.255.255.0 , default
gateway 192.168.1.254 .
Set the IP addresses to values that do not conflict: MICRO/I A IP address 192.168.1.6 , MICRO/I B IP
address 192.168.1.7 , computer IP address 192.168.1.8 .

Local network
• Set the IP address, subnet mask, and default gateway according to the local network environment being
used. When Automatically obtain the IP address is selected, the network settings are automatically
assigned from the DHCP server on the local network environment being used. Settings assigned from the
DHCP server can be checked on the Top Page in the System Mode.
• When Automatically obtain the IP address is selected, note the following points:
- It takes some time to acquire the network settings. If the download fails, increase the timeout time on
the Home tab, in the Project group, in Comm.Setup. For details, refer to Chapter 24 “1.3 Change
Communication Settings” on page 24-5.
- According to the DHCP server specifications, the IP address may change by removing and reinserting
the Ethernet cable.
- After connecting the MICRO/I into a different network, turn the power to MICRO/I off and then on again.
Automatically obtain the IP address (DHCP).: Automatically sets the network when connected to a network.
Use the following IP address:
Manually specifies the IP address, subnet mask, and default gateway.
IP Address:
Specifies the IP address. (Default: 192.168.1.6)
The format is “xxx.xxx.xxx.xxx”. “xxx” stands for a
numeric value from 0 to 255.
When connecting multiple devices to the same
network, make sure to assign each device a unique
IP address.
Subnet Mask: Specifies the subnet mask. (Default: 255.255.255.0)
The format is “xxx.xxx.xxx.xxx”. “xxx” stands for a
numeric value from 0 to 255.
This value must be the same for all devices.
Default Gateway: Specifies the default gateway. (Default: 0.0.0.0)
The format is “xxx.xxx.xxx.xxx”. “xxx” stands for a
numeric value from 0 to 255.
Set this value when using a router. Leave the value
blank when not required.
Port Number
Specifies the TCP port number (1 to 65535) to use for maintenance
